AClDlNQ-MACHINE FOR MAKING SHEET-METAL CANS.

SPECIFICATION forming part of Letters Patent No. 224,771 dated February 24, 1880. l

7 Application filed December 9, 1879.

To all whom it may concern:

Be it known 'that I, JAMES W. FARRELL, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Aciding-lvlachines for Making Sheet-Metal Cans, which improvement is fully set forth in the following specification and accompanying drawings, in Which Figurel is a top or plan View of the acid- Fig. 2 is a vertical section in line .90 m, Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

My invention relates to improvements in machines or apparatus for applying acid or flux to cans prior to dipping or soldering; and it consists of rollers or brushes rotating within acid-troughsand applying the acid to the wvman'ges of the can presented to said rollers or brushes.

Referring to the drawings, A represents a trough or tray for containing acid or flux to be applied to cans prior to dipping or soldering, said trough or tray being properly sup- 2 5 ported.

B represents a horizontally-arranged roller or brush, whose bearings are in suitable uprights or pieces a, rising from the trough A, and to its shaft or bearin g is connected a pulley or band-wheel, A, which receives power in suitable manner.

B B 13 represent horizontally-arranged rollers or brushes, which ale mounted on uprights or pieces a c a a a a rising from the 5 trough and located at an angle one to the other, so as to form a four-sided or other sided figure relatively to the shape of the can operated upon.

The roller or brush B is geared with the 4.0 roller or brush B, the roller or brush B with the roller or brush B, and the roller or brush B with the roller or brush B. If desired,

the roller or brush B may be geared with the roller or brush B.

O O O 0' represent a series of rollers or 5 brushes arranged, mounted, and geared similarly to the rollers or brushes B B B B, but located within the space of the latter rollers or brushes, and power is communicated to them by means of a pinion or spur wheel, D, which is connected to the shaft of the roller or brush 0, and gears with a pinion or spur wheel, D, on the roller B or its axis.

The bearings of the rollers O O G U are lettered b b b b, and are adapted to form supports for the head of the can to receive the acid.

The application is as follows: Power is communicated to the roller or brush B, thus rotating it, as also all the other rollers or brushes, B B B O O 0 0'. One head of the can is then placed on the supports b,.so that its flanges enter between the two sets of rollers or brushes in contact therewith, and as the saidrollers or brushes dip into the acid they 6 apply the sameto the two faces of each flange in a uniform, rapid, and inexpensive manner. The can is then removed and inverted and its other head applied to the rollers or brushes, and the aciding operations repeated with the above results.

If desired, one set of rollers or brushes may be mounted on a separate trough or tray, so that the two faces of the flanges may be acided at different times.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

An acidin g-machine consisting of or having rollers or brushes rotating withinan acid trough, and operating substantially as and for the purpose set forth.
